Compression Elbow Perfexim 735 20 mm x Female Thread 1/2"

Perfexim compression elbow 735 is a 90° fitting with a 20 mm compression connection and a female 1/2" thread (GW 1/2"). It is designed to join metal or plastic pipes to threaded components while maintaining a sealed connection in heating, plumbing and potable water systems. The compact angled body reduces the space required for directional changes and enables installation in confined areas where a right-angle transition between a 20 mm pipe and a 1/2" threaded fitting is needed.

Advantages

The compression design provides a secure, mechanically stable connection without the need for soldering or special tools, allowing for faster installation and easier maintenance. The 90° geometry permits neat directional changes and helps optimise pipe routing in limited spaces. The female thread offers compatibility with standard 1/2" threaded components used in residential and commercial installations, and the product is suitable for systems that require a sealed, pressure-resistant joint.

Suitable for

• Heating system pipework requiring a right-angle transition
• Domestic and commercial potable water installations
• Plumbing repairs and retrofits where space is limited
• Connecting metal or plastic tubing to standard 1/2" threaded valves and fittings

Key specifications

• Connection type: compression elbow, 90°
• Tube diameter: 20 mm (compression)
• Thread: female 1/2" (internal)
• Typical applications: heating, plumbing, potable water systems
• Installation orientation: right-angle connection for confined spaces

How to use

Ensure the pipe end is cut square, deburred and cleaned before assembly. Slide the compression nut and olive onto the pipe, insert the pipe fully into the fitting body, then hand-tighten the nut onto the female thread. Finalise the joint by tightening the nut with an appropriate wrench to the manufacturer’s recommended torque, creating a leak-resistant seal between the pipe, olive and fitting body. Verify alignment and test the system under working pressure to confirm there are no leaks.

Usage recommendations

Use the fitting only on compatible pipe materials and diameters; check that the pipe outer diameter is 20 mm and that threaded components match a 1/2" female thread. Follow local plumbing codes and ensure the system is depressurised before installation. Periodically inspect compression joints for signs of loosening or leakage, especially after thermal cycling or system maintenance.
